Abstract:
In this paper, a polynomial chaos (PC) approach
based on the concept of multi-fidelity algorithms is presented for
uncertainty quantification of multi-walled carbon nanotube
(MWCNT) interconnect networks exhibiting imperfect contacts.
The salient feature of the proposed approach is the development
of a new low-fidelity model where each MWCNT conductor is
represented as multiple parasitically coupled equivalent
conductors depending on the nature of the contact resistance of
each shell making up that conductor. This proposed low-fidelity
model is provably more accurate than existing low-fidelity
models, thereby leading to even faster construction of PC
metamodels than previously possible
